Description

[0001] The invention relates to a method for operating a logistics system and a logistics system.

[0002] From DE 10 2018 118 261 B4, a driverless transport system with a plurality of driverless transport vehicles is known, each comprising a base structure having a chassis and a battery-operated drive and a load-bearing device arranged above the base structure, wherein the load-bearing device of at least one driverless transport vehicle is supported on the base structure in a height-adjustable manner by means of a lifting device, wherein the lifting device is designed electro-hydraulically.

[0003] Furthermore, from DE 10 2020 005 987 A1 a system for transporting goods is known, which comprises at least one transport container for receiving goods, at least one driverless transport vehicle for transporting the at least one transport container and at least one transfer station, wherein the at least one transport container can be positioned at the transfer station, wherein the at least one transport container has a locking device which can be locked with a first locking unit of the at least one driverless transport vehicle and with a second locking unit of the at least one transfer station.

[0004] Furthermore, a storage, retrieval and processing system for processing objects is known from US 2022 / 0297935 A1.The storage, retrieval, and processing system includes a plurality of storage bins enabling the storage of a plurality of objects, the plurality of storage bins communicating with a bin conveyor system for moving selected storage bins to a storage bin processing location, a programmable movement device in communication with the bin processing location for receiving a selected storage bin from the plurality of bins, the programmable movement device including an end effector for grasping and moving a selected object from a selected storage bin, and a plurality of target bins in communication with the bin conveyor system for moving a selected target bin from a target bin processing location located proximate the programmable movement device to the plurality of target bins.

[0005] The invention is based on the object of developing a method for operating a logistics system and a logistics system which allows the driving modules to be equipped with different work modules quickly and, in particular, with minimal loss of time and to keep these reliably on the driving modules during operation.

[0006] This object is achieved by the features of claim 1 and claim 9, respectively. Advantageous and expedient embodiments of the invention are specified in the respective subclaims.

[0007] In the method according to the invention for operating a logistics system, the logistics system comprises autonomous driving modules, different work modules and parking stations, wherein a work module can be parked in each parking station, wherein each driving module together with one of the work modules forms an autonomous transport vehicle, wherein each driving module can charge the work module located there from each parking station equipped with a work module, wherein each driving module can unload its charged work module into a free parking station, wherein a takeover of one of the work modules takes place in such a way that the work module is mechanically contacted with the driving module and is transported by the driving module from the parking station in such a way,That the work module is held on the driving module solely by its weight, and that after leaving the parking station, the work module is mechanically locked to the driving module by a mechanism located on the driving module and / or the work module. This makes it possible to quickly equip the driving modules with different work modules, since the individual work module simply rests on the driving module in the parking station. Safe use of the work module during operation is then ensured by locking the driving module and work module outside the parking station.

[0008] It is further proposed that one of the work modules be handed over from one of the driving modules, with which it is connected to one of the autonomous transport vehicles, in such a way that, after completing a logistics task and before entering a free parking station, the work module is mechanically unlocked from the driving module by the mechanism present on the driving module and / or the work module in such a way that the work module is held on the driving module solely by its weight and that, after entering the parking station, the work module is decoupled from the driving module. This also allows a work module to be handed over to the parking station without delay, so that the time required for the overall process of changing the work module is further optimized.

[0009] It is also proposed that the contact between the work module and the drive module in the parking station be implemented in such a way that a contact plate of the drive module, intended to support the work module, is lifted by a lifting mechanism of the drive module in such a way that the work module is lifted from a support formed by the parking station. This process allows the parking station to be constructed in a simple manner and, in particular, without any moving components.

[0010] Furthermore, it is proposed that the disconnection of the work module from the drive module in the parking station be carried out in such a way that a contact plate of the drive module intended to support the work module is lowered by a lifting mechanism of the drive module such that the work module is placed on a support formed by the parking station. This process also allows for a structurally simple design of the parking station.

[0011] According to the invention, the locking is carried out in such a way that a contact plate of the driving module provided for supporting the work module is lowered by a lifting mechanism of the driving module in such a way that at least one bolt projecting upwards beyond the contact plate into a receptacle of the work module is moved from a release position into a holding position by a movement transmission mechanism formed between the bolt and the contact plate, wherein the bolt is pivoted in particular by means of a rotary joint.In this context, it is also proposed that unlocking be carried out in such a way that a contact plate of the driving module, provided for supporting the work module, is raised by a lifting mechanism of the driving module in such a way that at least one latch projecting upwards beyond the contact plate into a receptacle of the work module is moved from a holding position into a release position by a motion transmission mechanism formed between the latch and the contact plate, wherein the latch is pivoted in particular by means of a pivot joint. Accordingly, the lifting mechanism has a dual function, namely a lifting and unloading function with regard to the parking stations and an unlocking and locking function with regard to transport safety. Accordingly, a compact and lightweight design of the driving modules is possible.

[0012] Furthermore, the invention provides for the locking and / or unlocking of the work module with the driving module to be carried out in such a way that this occurs during the journey to an upcoming logistics task and / or on the return journey from a completed logistics task. This makes it possible to equip a driving module with different work modules with minimal time loss, since no additional time is required for locking and / or unlocking the work module and driving module.

[0013] It is also proposed to lock the work module to the drive module in such a way that the work module is held to the drive module in a form-fitting manner, particularly in a tilt-proof and / or energy-free manner. This reliably prevents the work module from shifting on the drive module, even under extreme loads, and also ensures that the work module remains securely held on the drive module even in the event of a power failure. Furthermore, the energy-free connection between the drive module and the work module also prevents any impairment of the drive module's range.

[0014] In the logistics system according to the invention, the logistics system comprises autonomous driving modules, different work modules and parking stations, wherein the freely available work modules are parked in parking stations, wherein each work module in use is carried by one of the driving modules when carrying out a logistics task and is locked to the driving module, wherein the driving module comprises a mechanism driven by a contact plate of the driving module, wherein the mechanism comprises at least one latch and wherein, on the one hand, an opening movement of the at least one latch is driven by a lifting movement of a lifting mechanism of the driving module acting on the contact plate and, on the other hand, a closing movement of the at least one latch is driven by a lowering movement of the lifting mechanism of the driving module acting on the contact plate.With such a logistics system, it is possible to reliably hold the drive modules on the drive modules during operation, wherein the logistics system is operated according to the method described in at least one of claims 1 to 8. This results in the above-mentioned advantages.

[0015] For the purposes of the invention, a driving module is understood to be a so-called driverless transport system, which is also referred to as FTS.

[0016] For the purposes of the invention, a work module is understood to be an attachment for the drive module, which can be designed for a wide variety of transport tasks as well as for a wide variety of handling tasks. For the purposes of the invention, a work module can also be designed as a robot that can be attached to the drive module.

[0017] According to the invention, a transport vehicle is composed of a driving module in the sense described above and a working module in the sense described above, wherein the working module is removably arranged on the driving module.

[0018] In the sense of the invention, a plurality of parking stations arranged at one location form a station.

[0019] Further details of the invention are described in the drawing using schematically illustrated embodiments.

[0020] This shows: Fig. 1: an exploded perspective view of a transport vehicle comprising a driving module and a working module; Fig. 2a and Fig. 2b: schematic representations of a mechanism present on the driving module and a detail of the working module; Fig. 3a-3g: a station with a number of parking stations, where the parking stations are occupied by different work modules; Fig. 4a-4c: schematic representations of the delivery of the first work module by the driving module to the first parking station and Fig. 5a-5d: schematic representations of the takeover of a second work module by the first drive module from a second parking station.

[0021] In the Fig. Figure 1 shows a perspective exploded view of a transport vehicle 1. The transport vehicle 1 comprises a driving module 2 and a working module 3.

[0022] The transport vehicle 1 is part of a logistics system LS. The logistics system LS comprises a plurality of preferably identical driving modules, for which the driving module 2 is typical, and a plurality of work modules, for which the work module 3 is typical. The plurality of work modules are at least partially designed differently so that they can perform different work tasks. For example, a first type of work module is designed for the transport of a wire mesh basket, and a second type of work module is designed for the transport of a single workpiece and, for this purpose, comprises a trough adapted to the shape of the workpiece.

[0023] Furthermore, the logistics system LS includes a large number of parking stations such as these as parking stations 4a to 4d in the Fig. 3a to 3g. The parking stations 4a to 4d are designed as a structural unit and form a station 5. The logistics system LS can also comprise several stations, each with any number of parking stations.

[0024] As it is from the Fig. As can be seen in Figure 1, the driving module 2 comprises a base body 6 and a head 7, which is designed as a lifting mechanism 8. The lifting mechanism 8 in turn comprises an upper part 8a and a lower part 8b, wherein the upper part 8a is formed by a contact plate 9. The contact plate 9 can be lifted from the lower part 8b by means of lifting cylinders 10a to 10d arranged in the lower part 8b.

[0025] In the assembled state of the transport vehicle 1, the work module 3, which is shown in simplified form on its upper side 3a, rests on the contact plate 9. On a Fig. 1, the work module 3 has four receptacles 11a to 11d, in each of which one of four projections 12a to 12d of the contact plate 9 is received when the work module 3 rests on the contact plate 9. In this way, the work module 3 is aligned with the travel module 2 and secured against displacement by forces acting laterally on the work module 3. Furthermore, the travel module 2 comprises a mechanism 13 by means of which the work module 3 can be locked to the travel module 2. This mechanism 13 comprises a first latch 14 and a second latch 15, which each project upwards beyond the contact plate 9 in the direction of the work module 3 through a first opening 16 and a second opening 17 in the contact plate 9.The latch 14 is connected to the contact plate 9 by means of a pivoting and sliding joint and has an elongated hole 14a through which a bolt 18 is guided, which is arranged in the region of the first opening 16 on the contact plate 9. The latch 15 is designed in a similar way and is shown in the . Fig. 2a and Fig. 2b is shown schematically in an enlarged view. Accordingly, the latch 15 is connected to the contact plate 9 via a pivoting and sliding joint and, for this purpose, has an elongated hole 15a through which a bolt 19 is guided, which is arranged in the region of the second opening 17 on the contact plate 9. A pivoting counter-bearing of the latch 15 is formed on the lower part 8b of the lifting mechanism 8. The first latch 14 also has a corresponding counter-bearing.

[0026] In the Fig. 2a, the second latch 15 is shown in a release position 15-I, in which it is when the contact plate 9 is released by the Fig. 2a, the lifting mechanism not shown in detail is raised and is thereby lifted off the lower part 8b.

[0027] In the Fig. 2b, the second latch 15 is shown in a holding position 15-II, in which it is when the contact plate 9 is moved by the Fig. 2b, the lifting mechanism (not shown in detail) is lowered and is approaching the lower part 8b. The second bolt 15 is moved in the manner of a KF guide.

[0028] By lowering the contact plate 9, the two latches 14, 15 are forced to pivot in opposite directions from a steeply upward position to a position close to a lying position. Accordingly, the distance between the heads 14b, 15b of the latches 14, 15 increases from the release position 15-I to the holding position 15-II. In this case, the latches 14, 15 spread out with their heads 14b, 15b into the corresponding receptacles 3c, 3d (see in particular Fig. 2a, Fig. 2b), which are designed and positioned on the underside 3b of the working module 3 in such a way that the latches 14, 15 pull the working module 3 against the contact plate 9 when the contact plate 9 is lowered.

[0029] In the Fig. 3a to 3g are, in addition to the above-mentioned station 5 with the parking stations 4a to 4d, the Fig. 1 known driving module 2 and the one from the Fig. 1 known first work module 3 is shown. Here, the Fig. 3a how the transport vehicle 1 formed from the driving module 2 and the working module 3 moves in the direction of an arrow P1 to the first parking station 4a. On the remaining distance to the first parking station 4a, the contact plate 9 of the driving module 2 is raised during the journey, so that the unloaded working module 3 is completely raised when entering the first parking station 4a and so that cantilever arms 20, 21 of the first parking station 4a slide under the first working module 3 when entering, wherein the cantilever arms 20, 21 form a support A4a for the working module 3. Here, the transport vehicle 1 is in the Fig. 3b shows how it has almost completely entered the first parking station 4a. Here, the transport vehicle 1 is in the Fig. 3c shows how it has completely retracted into the first parking station 4a. In the Fig. 3c is indicated by an arrow P2 that in a next step the contact plate 9 is lowered so that the working module 3 rests on the cantilever arms 20, 21 and is thereby lifted from the contact plate 9. Since the working module 3 is prevented from sinking further by the cantilever arms 20, 21 when the contact plate 9 is lowered, there is no locking with the driving module 2. A further, third arrow P3 is indicated in the Fig. 3c shows how the driving module 2 will move out of the first parking station 4a with the contact plate 9 lowered, leaving behind the first working module 3, in order to - as in the Fig. 3d and symbolized by a fourth arrow P4 - to move into the second parking station 4b under a second working module 22 with the contact plate 9 lowered.

[0030] The Fig. Figure 3e then shows how the driving module 2 is completely and precisely retracted into the second parking station 4b under the second working module 22. The arrow P5 is shown in the Fig. 3e indicates that in an immediately following step, the contact plate 9 will be lifted to lift the second working module 22 from cantilever arms 23, 24 of the second parking station 4b and - as in the Fig. 3f and indicated by an arrow P6—with the second work module 22 resting on the raised contact plate 9. Here, the cantilever arms 23, 24 form a support A4b for the work module 22.

[0031] From a comparative analysis of the Fig. 3f and Fig. 3g then shows that the contact plate 9 was lowered after exiting the second parking station 4b. According to the above explanations, the second work module 22 was locked to the driving module 2 outside the second parking station 4b by lowering the contact plate 9, so that an alternative transport vehicle 25 formed from the driving module 2 and the work module 22 can now assume a logistics task corresponding to the work module 22, and for this purpose, a secure connection exists between the driving module 2 and the work module 22.

[0032] In the Fig. 3a to 3g show two further work modules 26, 27 in the third parking station 4c and in the fourth parking station 4d. The work modules 3, 22, 26, 27 are each shown only schematically and—as explained above—are designed for different transport tasks. Thus, the driving module 2 forms a first type of transport vehicle 1 with the first work module 3 and a second type of transport vehicle 25 with the second work module 22. Thus, the driving module 2 can form a third type of transport vehicle with the third work module 26 and a fourth type of transport vehicle with the fourth work module 27. Of course, a second driving module, or a second driving module and a third driving module, can also be used.The basic principle here is that the LS logistics system, which comprises a multitude of driving modules and a multitude of work modules, is controlled by a control device in such a way that, through appropriate switching of work modules, a multitude of logistics tasks can be completed with minimal travel distances and in the shortest possible time. This involves a dynamic redistribution of logistics tasks depending on the number of driving modules in use and the number and type of work modules available.

[0033] For the purposes of the invention, the term logistics task is to be understood in such a way that it does not only include transport tasks in the narrower sense, but that it can also mean handling tasks or processing tasks or a mixture of the aforementioned types of tasks.

[0034] In the Fig. 4a to 4c is analogous to the Fig. 3a to 3g show again the delivery of the first work module 3 by the driving module 2 at the first parking station 4a in schematic side views. Fig. 4a shows the lifting mechanism 8 of the driving module 2 with its upper part 8a and its lower part 8b, wherein the upper part 8a - as described above - is formed by the contact plate 9 and the first working module 3 rests on the contact plate 9. The Fig. 4a shows the contact plate 9 already in its raised position, so that the latches 14, 15 are already unlocked from the first working module 3, the working module 3 is raised by the contact plate 9 and the working module 3 only rests on the contact plate 9.

[0035] As in the Fig. As can be seen in Figure 4b, the drive module 2 then moves with the raised and unlocked work module 3 into the first parking station 4a, so that the work module 3 is pushed onto its cantilever arms 20, 21. In the Fig. 4b, the contact plate 9 is already slightly lowered after the described retraction, so that the working module 3 already rests on the cantilever arms 20, 21 of the first parking station 4a.

[0036] In the Fig. 4c shows how the work module 3 remains on the cantilever arms 20, 21 of the first parking station 4a while the contact plate 9 is further lowered by means of the lifting mechanism 8. This further lowering is also symbolized by the fact that the position which the contact plate 9 has in the Fig. 4b, is indicated again with dashed lines so that its further decline is more clearly visible. Fig. In the position of the contact plate 9 shown in Fig. 4c, the driving module 2 is then completely decoupled from the working module 3 and can move out of the parking station 4a without the working module 3, for example to charge another working module.

[0037] In the Fig. 5a to 5d is analogous to the Fig. 3a to 3g show again the picking up of the second work module 22 by the driving module 2 at the second parking station 4b in schematic side views. Fig. 5a shows the movement of the drive module 2 with lowered contact plate 9 into the second parking station 4b, in which the second work module 22 is held. Fig. 5b then shows how the second working module 22 is increasingly lifted off the cantilever arms 23, 24 of the second parking station 4b when the contact plate 9 of the driving module 2 is lifted. Fig. 5c then shows how the second work module 22 is completely lifted from the cantilever arms 23, 24 by the contact plate 9 and the driving module 2 with the lifted work module 22 moves out of the second parking station 4b. Finally, in the Fig.5d shows how the second work module 22, after extending from the second parking station and the subsequent lowering of the contact plate 9, is locked by the bolts 14, 15 spread apart from one another and pulled towards the contact plate 9. The schematic side view shows how the bolts 14, 15 engage with their heads 14b, 15b in receptacles 22c, 22d, which open laterally and towards one another, on an underside 22b of the second work module 22.
